Attorney Kirk Nurmi told Judge Sherry Stephens the defense was resting after 38 days of testimony by 10 witnesses and then prosecutor Juan Martinez began calling rebuttal witnesses, starting with psychologist Janeen DeMarte.

DeMarte said she disagrees with defense experts Richard Samuels and Alyce LaViolette's diagnosis that Arias has post traumatic stress disorder.

DeMarte said Arias has borderline personality disorder.

"Borderline personality disorder, similar to what we see in teenagers often, sense of immaturity and emotional mobility general about instability, interpersonal relationship, emotions and sense of identity, meaning who am I as a person, constant fluctuation, manipulation, large sense of immaturity, think about a teenager," DeMarte described to the courtroom.

DeMarte also called LaViolette and Samuels' evaluations inappropriate, saying never in a clinical evaluation should the psychologist give gifts or show compassion toward the person they're interviewing, things both defense experts admit to doing.

The defense started cross examination late Tuesday afternoon which will continue at 9:30 a.m. on Wednesday.

The prosecution maintains Arias killed her ex-lover Travis Alexander in a jealous rage in June 2008. His body was found stabbed multiple times, his throat slit and he had suffered a gunshot wound to the head.

Arias claims she killed Alexander in self-defense. She faces the death penalty if convicted of first-degree murder.

On Monday, attorneys for Arias wanted to present new evidence to the jury.

Nurmi and Jennifer Willmott made the request before Judge Sherry Stephens, but the jury wasn't scheduled to be in the courtroom until the afternoon.
